To provide water tightness of the bladder in each wing the bladder material is coated with a special outer shell made of thermo-weldable polyurethane, during the production. It enables welding the bladder consisting of two parts and filling it with air.
Its parameters and quality translates directly into your safety and durability of the BCD. We can say with no exaggeration that it is one of the most essential parts of each wing and diving buoy.
In general, in wings and jackets shells of thickness from 0.08 mm to 0.2 mm are applied. In xDEEP buoyancy compensators we use materials coated with as much as 0.215 mm-thick TPU shell. The shells of higher thickness are more resistant to any damage that thinner shells. Consequently, it provides better safety of use.
